Rob made an excellent point re: CPR. On a vacation a few years ago we stopped at the entrance to Yellowstone Park. Another car stopped as well, and the couple (older) were kind enough to take our family photo. Then the woman explained they had just come from CA where they had buried their son. He had been an EMT in LA during the 1992 riots, and had contracted AIDS while performing CPR on one of the rioters.

Look at the bright side. You'll probably pick up some great tips on wardrobe selection.
